Atrioventricular Dissociation Differential Diagnoses

Ensure that AV conduction is intact, particularly in patients with accelerated junctional rhythm following cardiac surgery.
Diagnose and correct digoxin toxicity, if present.
Conditions to consider in the differential diagnosis of supraventricular tachycardia (SVT) with AV dissociation include the following :
- AV nodal reentrant tachycardia (AVNRT) with upper common final pathway block
- Junctional ectopic tachycardia (JET) with junctional-atrial (JA) block
- Orthodromic reentrant tachycardia with a concealed nodofascicular accessory pathway with nodal atrial block
- Intrahisian reentrant tachycardia with His-atrial block
